Tsuchigomori is a science teacher at Kamome Academy’s high school level. He has been working as a science teacher for a very long time, as he is secretly not a human. Instead he is a spider-like apparition who disguises himself as a human to help control the rumours about his wonder. He is the fifth wonder, and well he comes across grumpy, cryptic and sadistic in his true form, he truly does care for his students deeply and is a kind person when he’s his teacher self.
